INTRODUCTION: The beneficial effects of bivalirudin during primary PCIs are controversially discussed, data on unselected patients are rare. It was the aim of the study to compare bivalirudin versus heparin and provisional glycoprotein IIb/IIIa inhibitors (GPIs) in a "real-world" study. METHODS: From 05/2013 until 11/2014, the STEMI-patients in the Bremen STEMI registry were treated with periinterventional bivalirudin; before and after this period the standard anticoagulative treatment was heparin and provisional GPIs. RESULTS: In 714 patients bivalirudin was used for PCI, this cohort was compared to 683 patients with heparin and provisional GPIs. In patients with bivalirudin a significantly lower rate of hospital bleedings was observed compared to patients with heparin (4.6% vs 8.1%, P < 0.01, multivariate HR 0.57, 95%CI 0.35-0.93), in an exclusive analysis of severe bleedings a trend toward less bleedings was found in patients with bivalirudin (2.0% vs 3.5%, P = 0.07, multivariate HR 0.66, 95%CI 0.30-1.42). The rate of stent thromboses reinfarctions and mortality was not different between the bivalirudin and the heparin group. During 1-year follow-up bivalirudin was associated with a lower rate of bleedings and no significant differences in stent thromboses, reinfarctions, and mortality. Bivalirudin was not associated with an excess of bleedings or stent thromboses in subgroups that are regularly underrepresented in randomized trials (older patients, women, cardiogenic shock). CONCLUSIONS: In this "real-world" cohort of patients with STEMI bivalirudin compared to heparin and GPIs was associated with less bleedings and no significant differences in stent thromboses, reinfarctions, and mortality during hospital and long-term course.
